| 中文摘要: |
| 通过对合肥两处粘土和粉质粘土的室内龟裂实验,运用裂隙的统计方法和分形理论对不同温度条件下形成粘性土龟裂的表面结构特征进行了定量统计与分析,研究了龟裂发展与温度之间的关系,实验表明：龟裂的发育方式为三种,即极点推进式、平行推进式和环绕推进式；温度对粘性土表面龟裂长度、节点个数、条数、裂隙率和分维值等参数有重要影响,且对粘土和粉质粘土等不同土质的影响具有一定的差异性。 |
| 英文摘要: |
| By designing interior cracking experiments on clayey soil cracks from Hefei’s two areas and silty clay soil, in which the quantitative statistical analysis of crack and fractal theory is applied to the structural characteristics of crack surface of clayey soil in various temperatures, the paper reveals the influence of temperature on crack development. These experiments also show three ways of such development and a significant impact on the following parameters as length, number of nodes, number of fissure, fissure rate and fractal dimension of clay surface crack. Moreover, the influence differs in terms of clay and silty clay soil. |
